I may go a little bit deeper into the topic at a later time but for now I just want to share a Windows PowerShell based tool that I wrote to generate slitscan images from a 2D video the most simple way. By dragging and dropping a video-file. Continue reading Slitscan script→

Disclaimer: This posting is a work in progress. I’ve mode this some years ago and was asked to provide some documentation:

I have parts of a SAIA PCDII that I wanted to make use out of. The ourput boards have 6 relais each and 8 of them are connected to a backplane connector. This makes 48 mains voltage (low current) switchable channels.
Confusing what I mean? Have a look at this video

I’ve found some of the pictures I took while working on this and just a few days ago I found the box with the hardware itself.

For now the old pictures.

One of the output modulesI desoldered the ICs to work out the schematicdetailed picture of the output board sans ICsEight output boards in the extension case

I got both a genuine Manfrotto 323 and the 12$ ebay clone and took some pictures for you to compare. The Manfrotto one looks more valuable. The release lever of the clone is a bit loose bit holds the plates in very well. The Manfrotto plates fit the clone very well too.

I think the clone is good enough for what I’m doing with it so I will stick with it.

I have changed some details with the hosting of this site.
In theory everything should work as before.

What is this all about? Many old video camera (VHS era) are equipped with tiny black and white CRT screens as viewfinders. It is exactly these this posting is about. Many of them can be hooked up to a BAS or FBAS (Yellow RCA connector). Such as CCTV cameras or a Raspberry Pi to be used as a tiny screen or with the magnifying viewfinder assembly you can put it close to your eye and have a much larger image.
